All of the entries with WPCSL-generic/build/ are not part of the final product distribution, or they SHOULDN’T BE as of a bug fix made around April of 2013. I have not yet found where these entries are being generated. I’m guessing from the Codestyling Localization plugin that is scanning all of the files in the plugin directory.
If you are going to start a translation and notice that your server has a ./WPCSL-generic/build directory you can, and should, safely delete the entire WPCSL-generic directory from under the store-locator-le directory. In fact this is true of ANY site that has SLP installed. Not only does it save disk space, but removing any WPCSL-generic/build files will reduce the code living on the server which means less vectors of attack for hackers.
Leave the WPCSL-generic/classes directory. That is the correct production build of the wpCSL framework.
